Development of job cards for mechanical maintenance

Work in progress to develop job cards for mechanical maintenance personnel in nuclear power plants is described. Job cards are laminated 5 in.*7 in. cards containing a mix of informational graphics and text for important tasks involving mechanical maintenance equipment. They are organized by functional category, including general maintenance, pumps, valves, rigging, troubleshooting, alignment, V-belts and sheaves, documents, and system information. Card content is carefully developed to ensure that there are no conflicts with any controlled plant documents concerning the task. The job cards are in trial-use at two US power plants. The users include mechanics, trainees, job planners, and contractors. The authors summarize the methods used to identify the user and plant requirements for the job cards; the procedures adopted to specify content and packaging of the cards; the preliminary data documenting the job cards' acceptance, usability, and usefulness within the nuclear power plant environment.<>
